如何在python中下载pdf文件？

Question

我需要下载类似的东西

str = 'http://query.nytimes.com/mem/archive-free/pdf?res=9A00EEDE1431E13BBC4850DFBF66838A649FDE'
url = urllib2.urlopen(str)
file = open('test.pdf', 'w')
file.write(url.read())
file.close()

它只会创建一个错误的pdf.

我该如何将其写入文件？

Answer 1

您可以使用该pattern模块,该模块构建在最基础之上urllib2并具有更高级别的抽象.

from pattern.web import URL

url = URL('http://query.nytimes.com/mem/archive-free/pdf?res=9A00EEDE1431E13BBC4850DFBF66838A649FDE')
f = open('nytimes.pdf', 'wb')
f.write(url.download(cached=False))
f.close()
